ABSTRACT

A THERMAL NUCLEAR REACTOR WHICH OPERATES ABOVE THE CRITICAL PRESSURE AND TEMPERATURE OF THE REACTOR COOLANT. THE REACTOR COOLANT ACHIEVES SYSTEM OPERATING CONDITIONS BY MAKING THREE OR MORE PASSES THROUGH A CORE WHICH IS FUELED WITH NUCLEAR MATERIAL. IN ONE EMBODIMENT, THE REACTOR COOLANT SERVES AS A MODERATOR AND AS A COOLANT.
